drm: move drm based debugfs funcs to drm_debugfs.c

Browse Source 
Requirement is to create per client-id based directories to
hold key debugging information and for that access to
root debugfs dentry is need which is not in one place
and that information cannot be stored in drm_device.

Move the debugfs functionality from drm_drv.c and drm_accel.c
to drm_debugfs.c This enables debugfs root node reference
directly drm_debugfs.c and hence enable to create per client-id
directory.

v8: Create drm_accel dentry only if it's config is enabled (Jeff, Hugo)
v8: Merge drm_drv and drm_accel debugfs patches (Koenig, Christian)

v10: Since we moved drm_debugfs_root, hence to handle drm bridge
debugfs add a new function which call drm_bridge_debugfs_params where
drm_debugfs_root is accessible.
